Integrated single-cylinder engine base structure

Abstract

The invention relates to an integrated single-cylinder engine base structure which comprises a lower crankcase (1), a left balance chamber (2), a right balance chamber (3) and an oil pan (4), wherein the left balance chamber (2) and the right balance chamber (3) are symmetrically arranged at left and right sides of the lower crankcase (1); and the oil pan (4) is arranged at the lower parts of the left balance chamber (2) and the right balance chamber (3). According to the invention, the integrated single-cylinder engine base structure integrates a plurality of functions into a whole body and has high integration degree; three chambers are transversely arranged and three clapboards are longitudinally arranged, so that the longitudinal and transverse size proportion is proper, the integral rigidity is high, and the stability is high; a three-gear crankshaft bearing base is divided into a load-carrying bearing base and a thrust bearing base; the function division is clear; the load distribution is reasonable; the high working rigidity of a crankshaft and the working intensity of a bearing bush are ensured; and finally, the working intensity of the whole machine is improved.

Description

[0001] technical field [0002] The invention belongs to a component of a single-cylinder engine, and in particular relates to an integrated single-cylinder engine base structure. Background technique [0003] The single-cylinder engine is the basic platform for the performance research of the whole engine. Through this platform, it can provide the test basis for the power performance, economic performance and parameter matching of the future multi-cylinder research, and it is the test guarantee for the early research of the engine. As a single-cylinder machine base and a single-cylinder machine body, it jointly undertakes the role of the whole machine skeleton and system integration, mainly including the support and sealing of the whole machine, the construction and integration of the balance system and transmission mechanism, the engineering combination of the main bearing hole, the collection of lubricating oil and the integration of the transmission mechanism. Backflow, ...

AI Technical Summary

Problems solved by technology

However, the simple structural design inevitably has many deficiencies, such as the large ratio of the horizontal and vertical dimensions of the machine base structure, and the poor working stability of the whole machine; the support hole of the balance shaft has low rigidity, and the two supports are arranged, the balance block has a large radius of motion and high centrifugal force , the impact load of the machine base partition is too large; the machine base is relatively closed, and the adjustment ability of the mechanism is poor; the balance shaft has a single balance capacity, a high degree of specialization, and a low reuse rate; Poor maintenance performance, long cycle and other shortcomings
